Phys.org  July 10, 2023 Manganese (Mn) dendrites are a common type of mineral dendrite that typically forms two-dimensional structures on rock surfaces. Three-dimensional (3-D) Mn dendrites in rocks have rarely been reported, and so their growth implications have largely escaped attention. Understanding the dynamics of the growth of three-dimensional mineral dendrites is important for various fields of science—physics, geology, material sciences and even the study of extraterrestrial environments. An international team of researchers (Austria, Poland, UK) combined high-resolution X-ray and electron-based data with numerical modeling to give the first detailed description of natural 3-D Mn dendrites (in clinoptilolite tuffs) and […]
